Light: Science & Applications (LSA) publishes high quality optics and photonics research from around the world. The Journal covers fundamental research as well as the important issues in engineering and applied sciences that are related to optics and photonics.
What happens when a new technology is so precise that it operates on a scale beyond our characterization capabilities? For example, the lasers used at INRS produce ultrashort pulses in the femtosecond range (10-15 s), which ...
